Using Epoxy On Surfaces With Edges

31 January 2018

Preparation:Make sure you place some protective plastic down to prevent the epoxy from ruining your floors while the epoxy drips over the edges. We recommend painters plastic that is at least 2mil thick.

Bar rails and edges: When pouring the flood coat, the epoxy can be allowed to run over the sides which will create a coating on the vertical edges.

Underneath edge:Drips will form underneath the bar-rail or edge, these drips can be sanded off once the epoxy has cured with #200-300 grit sandpaper. If you catch the epoxy at just the right moment in the curing process, a razor knife can be used to cut the drips off.

Damming The Edges: When your application calls for a temporary dam to be constructed, it must be done with great care to ensure it can be removed after the epoxy is cured. Ideally, a smooth, soft or flexible plastic strip should be used because the epoxy will not stick to it. Alternatively, wooden trim can be used but only if it is first covered with a 2 to 4 mil plastic sheeting. Lining the wood trim with the plastic and taking it to the edge should prevent the epoxy from running in between the edge and the plastic. Testing on a small mock up should be done to ensure no leakage or problems will occur with your damming technique.

Calculating How Much To Buy: If you allow the epoxy to run over the edge, add a 25% waste factor for the material that will be lost.
